Why do we need a BOM?
You need your BOM to provide an overall part summary in one location. Lean or pull based manufacturing often favors a flat single-level BOM. Multi-level BOMs require more work and may require ERP software to use efficiently, but they come with the following advantages: Sub-assemblies can be copied to other products.
Why use single level BOM?
Single-level BOMs are good in cases where: The goal of the BOM is to give a broad overview of the product. Those using the BOMs do not need to see the overall structure of the product's design; electrical engineers, for example, may only need to see the wiring schematic. You need your BOM to provide an overall part summary in one location.
